Not all fence post caps are created equal, and buying by label size is the most common reason they don't fit. Here's how to match a cap to timber, Colorbond, hollow steel and retaining wall posts, and when a cap is doing real work versus just finishing the look.
"Galvanised" covers four very different finishes with very different lifespans. We break down what AS/NZS 4680 actually guarantees, how long a coating lasts by corrosivity zone, and where fence brackets really lose their protection on site.
Everything you need to spec steel retaining wall posts correctly: H-beam vs C-channel, how the 100/150/200 Series compare, and how to match posts to your sleepers.
